What are genetic crosses

KatRina [158]

Answer:

The correct option is C. Damage to myelination.

Explanation:

Multiple sclerosis can be described as a disease in which a person's body destroys his/her own myelin sheath. Myelin sheath is a protective sheath that covers the nerves. Hence, the nerves are not able to conduct signals. As the body's own cells destroy the myelin sheath, hence multiple sclerosis is an autoimmune disease. Multiple sclerosis remains a deadly disease as the proper cure to it has not yet been found.

When blood clots, an enzyme is activated to change a protein from one form into another.

exis [7]

Answer:

Hey mate!!

<h2>Process of blood-clotting</h2>

The mechanism to prevent excessive loss of blood from the body is called blood clotting.

<h3>Steps in blood clotting:</h3>

At the site of cut, damaged cells and platelets release thromboplastin.
This thromboplastin with the help of calcium ions,converts prothrombin into thrombin.
In the presence of calcium ions,thrombin reacts with soluble fibrinogen and converts it into insoluble fibrin.
Fibrin is a solid substance which forms threads and a meshwork at the site of cut.
Blood cells trapped in the network of fibrin.The blood shrinks and squeezes out the rest of plasma in the form of clear liquid.
The solid mass which is left behind is called clot.
